is a transverse section showing the parts depicted in-Figs. 2S and 29 placed together to complete the flushing rim 'shown in Fig. 27; Fig. 31 is a perspective view illustrating the elements shown in Figs. and 26 placed together.

In carrying out the present process. and referring mirticularlyto Figs. 1 to 16 both inclusive. there is provided a base 1 which shown in detail in Fig. l. the base being provided upon its upper surface with locking lug 2. The base 1 supports an integral table upon which is fashioned a pedestal 4 having oppositely inclined upper faces 5 and 6. the face 5 being longer than the facet. Surrounding the pedestal -l at the base thereof is a rib 7. hole 8 extends through the base 1 and through the table and around the hole is formed an annular rib or ring 9.

The invention includes a-pair of-casing sections, denoted generally by the numeral upper portions of the sections the same are cut away as shown at 17, so that in one end of the casing, when the casing sections are fitted together, there is formed a recess 18 which will be understood best from Fig. 15. Into the side portions of the recess 18 are inserted wedge-shaped blocks 19, one of which appears in Fig. 16. The adjacent faces of these blocks 19 are spaced apart so.

as to define an inwardly extended passage 20. At their lower ends, the casing sections 10 are shaped as shown at 21 so as to receive the table 3 of the base 1, reference being had particularly to Fig. 12. Above the portions 21, the casing sections 10 are cut away as shown at 22 so that a space exists around and above the rib 7 when the casing sections 10 are supported upon the base 1. In their inner faces, the casing sections 10 are provided with channels 23 which define a reduced throat 24 shown in Fig. 12. Above the channels 23, the casing sections 10 are laterally enlarged as shown at 25 in Fig. H to define a basin 26 (Fig. 12). Around the upper edges of the laterally enlarged portions 25 are formed grooves 27 having communicating notches 28 therein, the casing sections being provided upon their upper faces with superficial recesses 25) which communicate with the notches 28. Depressions30 are formed in the upper faces of the casing sections 10, and at this point it will be understood that in the lower faces of the casing sections, similar depressions are formed, which last named depressions receive the'lockingdn 's 2 on the base 1.

The invention further includes a bowl core 31 shown in detail in Fig. 6. The bowl core 31 is provided with a flange The bowl core projects downwardly into the basin 26 and the flange 32 fits in the groove 27. The bowl core 31 is provided with a lug 33 which fits into the notches 28. The lower face of the bowl core 31 iss inclined as shown at 31 and the core terminates in a downwardly extended nose 3!) which is disposed above the hole 8 in the base 1. The flange 32 may be grooved as indicated at 32. The lug 33 maybe grooved or slit as shown at 36.

ably in the bore 53.

. The invention includes a lid or cover 37 shown in detail in Fig. The'lid 37 is equipped with lugs '38 which register in the depressions .30 of. the casing sections, 10. Upon the lower faceof the lid 37 is formed a tongue 3911411011 fits into the superficial tion. that if desired, the bowl core 31 and the lid 37 may be made in one piece. The lid 37 is provided with a pouring hole .13 alined with a pouring hole 44 in the bowl core 31. these details being shown most clearly in Fig. 2.

An outlet forming plug 45 constitutes a partof the invention. this element being dclineated in detail in Fig. 3 and being shown in place in Fig. 2. The plug 45 at its lower end is tapered. but its upper end may be of cylindrical form as shown at 46. The upper end of the portion 46 of the plug 45 is beveled or concaved as shown at 41'. The plug 1:") is mounted in the opening 8 in the base -1 and the beveled or concaved end 47 of the plug lies above the ring 9.

The invention further includes a primary former -18 shown in detail in Fig. 13. The former 43 includes a head -19. the inner end wall of which is shown at 50. Projecting inwardly from this end of the head of the former is an arm 51. inclined along its lower edge and adjacent the end wall 50 of the head 19, as shown at 52. The former 43 is provided with a bore 53 and the outer end face of the head 49 of the former is inclined as shown at 51 so as to stand at right angles to the axis of the bore 53. The primary former 43 includes a tip 55. concaved as shown at 51' upon one end. rod 57 is anchored at one end in the tip 55 of the former. the rod 57 being received slid- Threaded onto the outer end of the rod 57 is a lever nut 58 or its equivalent. adapted to bear against the inclined end face 54 of the former. The primary former 18 is inserted into the opening 20, the concavcd end face 56 ot' the tip receiving the plug 45. A secondary former 5!) is provided. the same being shown in detail in Fig. 11. The former 59 includes a head ()0 to the outer end of which a bandle (31 is secured as shown in Fig. 2. The inner end wall of the head 0 is shown at (32 and inay be provided with an inwardly projecting rib63. l.rojccting from the inner end of the head ('30 of the sccoiulary former of) is an arm (31- having an inclincdcml face above which is located a notch 66. The secondary former 59 is inserted into the upper portion of the -opening'20 above the primary former 48, the head 60 of the secondary former being'received in the notch 42 of the lid 37. The parts now appear as shown in Fig. 2 and when the slip is poured in through the holes 43 and 44, there will be fashioned a product of the type illustrated in Fig. 1, saving for the fact that theupper ring of the article has not yet been. completed nor part 81 attached.

The completed latrine or closet shown in Fig. 1 may be described briefly as comprising a bowl 67 provided with a tubular outlet 68 having a flange 69, the lower portion of the bowl 67 being connected with an apron having a flange 7 3. Located within the contour of theapron is an inclined water table 71 connected with an oppositely inclined partition 72. Located above the partition 72 is a tongue 7 4, one end of which is denoted by the numeral 75. The other end of the tongue 74 is depressed as indicated at 76 and merges into the bowl 67. Located above the tongue 74 is a spoon 77, the outer edge of which merges into the bowl, the inner end of which is downwardly inclined as indicated at 78, the end 78 being disposed above the depressed end 76 of the tongue 74. a

When the slip is poured into the mold shown in Fig. 2, the structure above described will be produced and to avoid a lengthy description, a table is inserted hereinafter, in one column of which are placed the parts of the latrine. and in the other column of which are placed the corresponding parts of the-mold. A reference to this table and an examination of Fig. 2 will explain thoroughly the functions of the parts of the mold in the making ofthe finished product.

Referring to Fig. 1 and noting the foregoing description, it will be observed that an opening 79 remains in the front wall of the bowl 67 of the latrine..this opening being grooved as shown at 80.

Part of product. Part of the mold.

A closure for the opening 79 is provided, this closure being denoted by the numeral 81 and being shown in detail in Fig. 10.,

The closure 81 is fashioned in a pair of cooperating mold members 82 and 83, depicted in Fig. 7, one of these mold members being provided with a pouring hole 84. After the closure 81 has been formed in the manner above described, the closure is mounted in the grooves 80 of the opening 79 in the bowl of the product.

The flushing rim 85 is shown in Fig. 27, and in this connection Fig. 27'may be com pared with Fig. 1. The rim 85 comprises an The mold in question comprises a top sec tion 95 and a bottom section 94. There are 1 recesses 154 in the top section 95 which cooperate with lugs 155 on the bottom section 94, to prevent the sections from slipping laterally on each'other. In the top section 95 there is formed, as shown in Fig. 23, a groove 96 at the base of which there is a slot-156. On the bottom section 94 there is a rib 97 whichis' received in the groove 96, the rib 97 being provided with indentations 'or marks of some sort, indicated at 158 and adapted to show where the outlet perforations are to be pierced in the finished product. Upon each side of the rim 97 there are smaller ribs 98. There is a pouring hole 153 in the part 95 and air escapes through vent slits 157. The hinge lug 100 is formed partly in a recess 207 formed in the upper member 95 and. the inlet opening 200 is shaped by an inwardly flaring. lug 208 on the part 94. There is a slot 159 adjacent the lug 208 which forms the lip 201. The holes 209 in the hinge lug 100 are formed by 00- operating bosses 210.

The parts 94 and 95 of the mold in which the lower member 87 is formed are disposed as shown in Fig. 22 and the slip is poured in through the hole 153. The lower member 87 of the flushing rim is thus formed, 'as indicated in Fig. 29, .the slot 156 forming the tongue 206.. The upper member 86 of the flushing rim is formed in a mold shown in Fig. 31 and comprising a top member 88, shown in Fig. 26 and a bottom member'89 shown in Fig. 25. The bottom m'ember 89 is provided with'a groove 90 and has air slits 152. This element of the mold is provided with bosses 150. The hinged lug recess is shown at 101. The top member 88'of the mold shown in Fig. 26 is provided with recesses 151 which receive bosses 150. The top member 88 includes a rib received in the groove 90. reference being had to Fig. 8. Upon each side of the rib 92, recesses 91 are formed. The top member includes a tapered lug 211 which aids in forming the inlet 200. Cooperating bosses 153 on the members 88 and 89 serve to aid in forming the holes 209 in the hinge lug. The-parts SS'and 89 are superposed upon each otheras shown in Fig. 31 and the slip is poured into the mold through the pouring hole 212. By this operation, the upper. member of the mold will beformed, substantially as shown in Fig. 8. The ribs 98 form grooves 99 in the edges of the lower member 87 of the rim and the recesses 91 form ribs 99 on the upper member 80 of the rim. The top section 95 is then placed on the bottom section 89, as shown in Fig. 30, the grooves 99 receiving the ribs 99" on the finished product. Thus, the constituent members 86 and 87 of the rim are brought together, and, after a sufficient period of time has elapsed, the members 95 and 89 shown in Fig. 30- may be separated,

whereupon the complete flushing rim 85 is placed upon the bowl of the mold, the tongue 200 on the flushing rim cooperating and coalescing with the bowl of the mold.

In Figs. 17 to 21 inclusive, a modified form of mold is shown. This mold resembles in-most particulars, the structure hereinbet'ore described, and the description of that form of the invention under consideration may be shortened accordingly. Reierring to Fig. 17, the base is indicated at 102 and the table at 103, the rib being shown at 101, the same corresponding to the pedestal 4. The ring 105 corresponds to the ring 9. In the base 102 an opening 100 is formed. The

casing sections are shown at 107. A single wedge block 108 replaces the wedge blocks 19 before described. In the wedge block 108 there is a hole 109 and in the upper-edge of the wedge block an inclined groove 110 is formed. The wedge block is provided with a tapered or pointed extension 111. The bowl core is shown at 112 andthe lid at 113, the same having pouring holes 11%. The nose of the bowl core is shown at 115. The secondary'former is designated bythereference character 116 and is engaged slidably in the groove 110 of the block 108. The primary former 117 is inserted through the hole 109 in the block. The outlet forming plug appears at 118. The product produced" in the mold under discussion differs from the product shown in Fig. 1, in that'the product produced in the mold shown in Fig. 17 is provided with a central core which, when the pouring operation has been completed. is open at one end as indicated at 120. The opening in the wallof the bowl hereinbefore described, isshown at 119. In this form of the invention, two closures therefore instead of one are required. The lcsurc. for the opening 119 is shown in detail in Fig. 19 and is indicated by the reference character 121, this closure being fashioned in a pair of cooperating mold members 122 and 123 shown in Fig. 18,one of which mold members is provided with a pouring hole 121. The closure for the opening 120 is indicated by the reference character 125 and is shown inFig. 21. The closure 125 is made in a mold comprising cooperating members 126 and 127, one of which has a pouring hole 128. The closure 125 is first mounted in place in the opening 120 and then the closure 121 is mounted in the opening'119.

In practical operation, the parts are positioned' as shown in Fig. 2 and the slip is poured into the mold through the opening iii-11. In one method of procedure, after the slip has set sufliciently, the entire mold is inverted, so that the same rests upon the lid 37. Then the secondary former 59 is removed by means of the handle 61. The lever nut 58 is removed from the rod 57. The body portion of the primary former 48is slid off the rod and subsequently the rod together with the tip'55 is removed. The plug 45 may be detached from the part 1 and'the same may belifted off 'the'product, the easing sections 10,'the member 37 andthe bowl core 31' subsequently being removed. I

Obviously, the foregoing steps may be varied but, generally considered, it is desirable that, whatever course of procedure be followed, the secondary former 59 be removed before the primary former 48 and its tip are taken out. i

It is to be observed that the faces of the cooperating parts of the structure, asshown in Fig. 2, are spaced apart by a distance equal to the thickness of the finished product.' There is no occasion. therefore, for tap-v ping to let the slip out of internal chambers or pockets. Further, the entire process may be carried out at once, and thereis no occasion for permitting an extended period of time toelapse between the formation of one part of the product and the formation of another part thereof. i I

As is well understood in the art, the parts of the mold are ordinarily inade of plaster of Paris or some similar substance which will take the moisture out of the slip'with suflicient rapidity. As will be appreciated ,by those skilled in the art, the slits 41, 36

and 32 constitute air vents.

Especial'at'tention' is directed tothe fact that the part 49'51 ofthe former 48 may part 49-51 of the 1. A mold of the class described comprising cooperating bowl forming elements and cooperating siphon passage forming elements, the respective cooperating elements being spaced from each other by a distance representing the thickness of the wall of the bowl and siphon passage of the finished product; and means for admitting slip between the cooperating elements.

A mold of the class described comprising a casi'ngliaving an opening in its side wall, and comprising cooperating parts; and a removable passage former slid-ably insertible and removable with respect to the casing through the opening in the side wall while the said parts of the casing are in cooperating relation.

A mold of the class described comprising a casing having an opening in its side wall, and comprising cooperating parts; and a pair of superposed passage formers slidably insertible and removable with respect to the casing through the opening in the side wall while the said parts of the casing are in cooperating relation.

4. A. mold of the class described comprising a base; a casing resting thereon; an outlet forming plug inserted into the base; and a passage former removably inserted through theside wall of the casing and cooperating with the plug.

5. A mold of the class described comprising a casing: a bowl core therein; and a laterally extended removable passage former projecting through the outer wall of the casing and cooperating terminally with the bowl core.

In a device of the class described, a base; a casing resting thereon; a bowl core within the casing;ran outlet forming plug insertible through the base; and a pair of laterally removable formers carried by the casing, one former cooperating with the bowl core and the other former cooperating with the plug.

A mold of the class described comprising a casing and a passage former inserted through the side wall of the casing, the passage former being provided with a removable tip. 7

10. A mold of the class described comprising a casing; and a passage former inserted through the side wall of the casing, the passage former including a body portion and a removable tip, the tip having a rod passing through the body portion of the former, the body portion of the former beingremovable, along the rod, independently of the tip.

11. In a device for forming the coacting parts of a flushing rim, a pair of molds each comprising a primary member and a secondary member cooperating with the primary member, the primary member having a groove and the secondary member having a tongue registering in the groove, one secondary member having concavities upon opposite sides of its tongue and adapted to form tongues on one part of the rim, the other secondary member having ribs upon opposite sides of its tongue and adaptedto form grooves on the other part of the rim, the ribs of one secondary member being shaped to correspond to the concavities of the other secondary member, and the primary members being adapted to be placed together to cause the tongues and the grooves on the parts of the rim to coact.

In testimony that I claim the foregoing as my own. I have hereto atlixed my signature in the presence of two witnesses.
